The autopilot was supposed to have maintained the altitude of the aircraft at 2000 feet. Unfortunately it did not do so and the aircraft gradually descended.
The crew was so focussed on the faulty wheel indicator light that they failed to monitor the functioning of the autopilot. A glance at one of the three altimeters (altitude indicators) in front of them would have immediately alerted them that the autopilot was not maintaining the altitude.
When the co-pilot suddenly recognised that there was a problem with the altitude it was too late.
The aircraft crashed nearly twenty miles from the runway.
Co-pilot: We did something to the altitude Captain: What? Co-pilot: We're still at two thousand right? (we are still flying at 2000 feet ?) Captain: Hey, what's happening here? [Sound of click] [Sound of six beeps similar to radio altimeter increasing in rate] (special type of altimeter alarming that altitude is decreasing) [Sound of impact]
